Identifying Igneous Rocks
Igneous rocks are one of the three main classifications of rocks, and they are formed both above and below ground. Learn about the intrusive and coarse-grained nature of igneous rocks with help from a lab manager and research scientist in this free video...
Igneous rock (derived from the Latin word ignis meaning fire) is one of the three
main rock types, the others being sedimentary and metamorphic. Igneous rock is
Intrusive igneous rocks crystallize below Earth's surface and the slow cooling that
occurs there allows large crystals to form. Examples of intrusive igneous rocks ...
This video explains the origin of these varied rocks
and the minerals that compose them. Rock
formed from deep magma is called "plutonic." Since it takes a lot of heat to form magma or lava, igneous rocks
form where plates come together, where continental crust is pus... More »
